I need some information in regards to 14081044 BBC heads which are currently on a running 454, in a motor home. Many sources state they have a 113cc open chamber (which would up the compression about a 1/2 point over 118 cc heads, right?) , 2.06 intake and 1.72 exhaust valves, and are oval ported.

Without tearing down the engine, I'm trying to find out if the ports are the small "peanut port ovals" or the larger oval ports that would flow better at 4,000 to 5,500 rpm.

Thanks for your help and support!
